AUGUSTUS PLINTA, OF ALBANY, NEW YORK.

RAILROAD-RAIL.

Specification of Letters Patent No. 22,376, dated December 21, 1858.

To all whom it may concern:

Be it known that I, AUGUSTUS PLrN'rx, of the city of Albany, State of New York, have invented a new and useful Improvement in the Construction of RailroadsRails; and I declare the following specification, with the drawings hereto attached as part of the same, to be a full and perfect description thereof.

Similar letters in the Various figures denote the same parts of the rail.

My rail A is a hollow tube of the ordinary length of railway bars, whose cross section externally and the cross section of its hollow7 space B is radically an ellipse as shown in Figs. l, 3, 4, or oviform as shown in Fig. 5 (a, Z), c, d, f). The lower portion of the rail is formed into a foot, or flange K, 4 K, being a part of its solid structure and a lateral extension of the lower portion of the arch for the entire length of the rail. The inward segment of the upper arch is to be extended by a projection or lip g of proper size and form as a face for the tread of car wheels and a guard to keep the ianges of the wheels from rubbing against the rail.

At each end of the rail for purposes connected with apparatus for securing the ends of the rails to each other, (as the same is described in the Letters Patent for improvement in securing the ends of railwaybars, granted to me on the 9th November 1858,) a slot m of several inches in length is to be made through the bottom of each rail extending from the end of the rail inwardly, or the said slot continued for the whole length of the rail, for convenience of construction and use. Also a transverse slot 7L, L, is to be out at each end through the lower part of the body of the rail, for the purpose stated in said patent.

The rail is to be secured by the usual hook headed spike passing through square notches 0 cut out of the flanges, or in any suitable way.

I claim The construction of a. railway rail by forming the same hollow, of an elliptical or oviform shape, in cross section, the lower portion of the arch being extended into a foot or flange, and a segment of the upper arch being extended into a lip or face for the tread of car wheels, slots being made through. the bottom, and across the lower part of the body of the rail, substantially in manner and form and for the purposes set forth in the within specification.

A. PLINTA.
